After a couple of days putting this purifier on my car, I can say that It's really helpful to remove the dust in the small area. Especially, during summer when driving with window down a lot of smoke, dust will coming into my car. It works really well and I can feel the clean air after a couple of minutes turning this device on. It's super quiet even in the high-performance mode.
Purchased this unit due its technology and portability. It works as described and is super lightweight and quite. The diameter is similar to a 16 oz water bottle. Easy to carry by hand or in handbag/backpack. Works via usb cable, would be perfect if it had a rechargeable battery.
The packaging is very exquisite, there are several gears, the wind is very strong, and the smoking can be purified quickly, which is very powerful
Allergies have been significantly better since putting this in my office. It’s quite and isn’t an eyesore on my desk.
